Storyline

When his friend Professor Kingsley is at deaths door, brain surgeon Dr. Sovac saves his life by means of an illegal operation that transplants part of injured gangster Red Cannon's brain. Unfortunately, the operation has a disastrous Jeckll and Hyde side effect and under certain conditions the persona of Cannon emerges. Sovac soon learns of the duel personality and of half a million dollars the gangster has hidden away. He attempts to find the money through the manipulation of his friend, an attempt that brings Kingsley closer to madness as he alternates between a meek professor of English and a brutal gangster out for murderous revenge on those who tried to kill him.

Trivia

Upset about the critical acclaim that Bela Lugosi received for his portrayal as Ygor in Son of Frankenstein (1939), Boris Karloff refused to ever play the monster again, or to appear in another film opposite Lugosi, unless he was the star with the most screen time. This explains why Karloff appropriated the doctor role that was written specifically for Lugosi in this, their next major film, leaving the Astro-Hungarian to play a minor, American gangster part, and forcing script changes to remove references to the doctor's past in Vienna, since Karloff spoke with a British accent. It also explains their final pairing, with Karloff securing maximum screen time in The Body Snatcher (1945), while having Lugosi relinquished to a "barely there" janitor role. See more »

Wonderful melodramatic hooey
8 September 2005 | by See all my reviews

In order to save a friend's life (Ridges), Dr. Ernest Sovac (Karloff) must perform a "brain transplantation" using the brain from a gangster (also played by Ridges). It is an illegal operation and one that has horrifying results. I must admit I had a hard time getting past the idea that a man who had a brain transplant would make up and still be himself (and not the person whose brain he now had), but once I did I enjoyed all the wonderful melodramatic hooey. Karloff is great in his role as the caring doctor with a sinister motive for saving his friend's life and Lugosi is super in his unusual role as a gangster (despite his European accents). But Stanley Ridges stole this show and did a perfect job with his Jekyll and Hyde personas.
